Our tree has been blown over. 
The branches that extended over a neighbour's garden have damaged her fence. I don't know what has happened inside her garden.
We regularly prune and maintain the parts of the tree within our garden.
Who is responsible for repairing the fence? What about damage inside the neighbour's garden?
We are cordial neighbours, though not friends. We are both aware that we have the right to prune to the boundary, but neither of us take full advantage of this if we like the other's plant that is encroaching on our garden.
What I'm wondering is, if you choose not to prune a branch that is growing into your property, does it mean that you accept responsibility for any damage that it does?
I'm not trying to swerve any responsibility. If it's all my responsibility, then I will pay for the repairs.
